I have this shaking when I have overdone activities. It is really noticeable in my handwriting.
I am journaling everything I am on the fourth month of doing it daily. I try to journal Blood pressure heart rate, all medications, and supplements. What I do actively, how long it takes, my sleep, my pain level and my activity level. I am trying to really work out my personal energy envelope so I can safely take part in life again a bit more.
When I have PEM you can see it in my handwriting. My whole being seems to tremor, it shows in my hands!
Getting dehydrated is right up there with doing too many chores, or having too many face to face conversations.
Best of everything to you
